[Phospholipid fatty acid composition of microorganisms in pine forest soils of Central Siberia].
The phospholipid fatty acid (PLFA) composition of microorganisms in podzolic soils of pine forests of Central Siberia was studied. The living microbial biomass gradually decreased in the studied mineral soil layer from 0 to 1 m. Despite a twofold drop in biomass in the lower layers, its level remained sufficiently high (12-14 nmol FA/g soil). The coefficient of similarity of fatty acid composition of soils of forested and open sites was 0.85. The fatty acid richness decreased and distinctions in fatty acid profiles increased with depth of the mineral soil layer.
